Hydrocarbon pyrolysis of sulfur-containing feedstock

The present disclosure relates to methods, apparatuses, and systems for removing sulfur compounds from a heavy hydrocarbon feed as part of a steam cracking process for producing light olefins. In at least one embodiment, the method includes introducing a hydrocarbon feed having a first sulfur content into a steam cracker to produce a steam cracker effluent having a second sulfur content that is less than the first sulfur content. The method includes introducing the steam cracker effluent to a fractionation system to produce a light hydrocarbon product stream having a third sulfur content less than the second sulfur content. 本公开内容涉及从重质烃进料中除去硫化合物的方法、装置和系统作为制备轻质烯烃的蒸汽裂化工艺的一部分。在至少一个实施方案中，所述方法包括将具有第一硫含量的烃进料引入蒸汽裂化器中，以产生具有小于所述第一硫含量的第二硫含量的蒸汽裂化器流出物。所述方法包括将所述蒸汽裂化器流出物引入分馏系统以产生具有小于所述第二硫含量的第三硫含量的轻质烃产物料流。
